COMBINED LOOM SHUTTLE-BOX FRONT GUARD AND GUIDE PLATE.

Application filed December 28, 1922.

To all whom it may concern.

Be it known that I, PARKER J. JoNEs, a citizen of the United States, and resident of Chicopee, county of Hampden, State of Massachusetts, have invented an Improvement in Combined Loom Shuttle-Box Front Guards and Guide Plates, of which the fo-llowing description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to means for guarding the shuttle and guiding it into the shuttle box at the replenishing end of an automatic filling replenishing loom of the type wherein a cover plate and front binder is provided for the shuttle box and wherein the shuttle feeler is employed having its path of movement across the lay at the mouth of the shuttle box.

The invention is particularly useful in a so-called broad loom where the shuttle has a comparatively long flight.

The object of the invention is to insure that the tip of the shuttle shall be prevented from coming into direct striking engagement with the guarding device. This not infrequently happensin the type of 100111 referred to and results in breakage or damage to the guard plate, breakage or damage of the shuttle, or the slowing up of the shuttle so as to cause it to be improperly or incompletely boxed.

The object of this invention is to provide in the type of loom referred to a combined front guard and guide plate, the. former acting in the usual manner to guide the shuttle after it is started into the box and the latter located inwardly from the path of the shuttle feeler and acting to receive the blow of the incoming shuttle in such a manner as to prevent contact of the tip of the shuttle therewith and thus injury either to itself or to the shuttle and acting further to guide the shuttle smoothly into engage ment with the guard plate and thus insuring its proper boxing, all without in any way interfering with the usual location and path of movement of the shuttle feeler.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims. 1

The present invention having to do only with this single feature of the loom it is Serial No. 609,481.

necessary here to illustrate or describe only those parts of the 100111 directly concerned therewith, the general construction and operation of this type of loom being well known and familiar to those skilled in the art.

In the drawings: 7

Fig. 1 is a top plan view of a portion of an automatic filling replenishing loom of the type in which the shuttle box at the re plenishing end of the lay is provided with a front binder and a cover plate and in which a shuttle feeler has its path of movement across the lay at the mouth of the shuttle box and beneath the cover plate, the drawing showing in connection therewith a preferred form of construction embodying the present invention;

Fig. 2 is a view in front elevation of the construction shown in Fig. l with a portion thereof broken away.

A small portion of the loom frame 1, lay 2 and lay sword 3 at the right hand orreplenishing end of the loom is illustrated. The shuttle box at this end is shown as formed at the rear by a rigid back plate 4, at the top by a cover plate 5, at the front by a movable binder 6 faced with leather 7 and at the bottom by the race plate 8. These parts are in general of the usual form employed in this type of loom and particu larly in the so-called broad loom. The shuttle 9 upon entering the box pushes forward the front binder 6 which swings about the right hand end and is yieldingly pressed rearwardly by a suitable spring, not shown.

In this type of loom a shuttle feeler, which may be of any usual and well-known construction, at the proper time moves rearwardly across the lay directly inwardly, or toward the center of the loom, from the inner tip of the shuttle or, in other words, across the mouth of the shuttle box so as to ascertain if the shuttle is properly boxed and to stop the loom by contact with the shuttle if the shuttle projects from the shuttle box. Such a shuttle feeler is assumed as moving transversely of the lay from front to rear in a path generally indicated by the elevated portion 10 of the cover plate which is shown elevated in the usual manner to allow the passage of the shuttle feeler therebeneath;

A preferred form of construction embodying the present invention is illustrated and comprises a single integral structure such as a casting comprising essentially the front guard plate 11 and the front guide plate 12 which, in the preferred form shown, are thus integral with a depending base 13. The front guard plate and the front guide plate are rigidly secured to the lay in their proper positions and, in the form shown, this is secured by bolting the depending base 13 to.

the front face of the lay by bolts 14. This base may also be provided, as illustrated, with a bearing boss 15 to receive the journal of the usual protector finger, the operation of which is controlled by the front binder 6 to operate the usual brake and protector mechanism.

The front guard plate .11 extends well above the medial line of the shuttle 9, as seen in Fig. 2; it presents a forwardly curved inner end 16, that is to say, the end of the plate toward the center of the loom is formed in a smooth curve extending toward the front of the loom; the plate also extends outwardly or toward the right hand end of the loom parallel with the back plate for ashort distance to form an inner front wall'at the mouth of the shuttle box; and at the top this guard plate is provided with a strengthening flange 17 while on the face of the outwardly extended portion is formed a longitudinal groove 18 to receive the filling extending from the shuttle to the fell.

It will thus be seen that the inner end of this front guard plate is located at the mouth of the shuttle and sufliciently ,to the right of, or outwardly from, the path of the shuttle fe'eler not to interfere therewith.

The front guide late 12 is located entirely to the left of, or inwardly of, the path of the shuttle feeler so as not to interfere therewith. This front guide plate at its inner end curves forwardly as indicated at 19 in Fig. 1 and downwardly as indicated at 20 in Fig. 2. The top edge of this guide plate 12 is shown about in line with the tip or point of the shuttle as it rests upon the lay so that the curved inner end 19 and 20 of the guide plate extends to a point well forward of and well below the path of the tip of the shuttle as it travels toward the box. Consequently it is impossible for the point or the tip of the shuttle to strike diit is impossible for the point or tip of the shuttle being thus guided to engage directly any'portion of this guard plate. As a result the shuttle is, therefore, by this invention directed smoothly and easily into the box notwithstanding the necessary provision for the path of movement of the shuttle feeler.

The surfaces of the guard and guide plates are finished and polished off in the usual manner to reduce friction.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent, is:

1. In an automatic filling replenishing loom of the type in which the shuttle box at the replenishing end of the lay is provided with a front binder and a cover plate and in which a shuttle feeler has its, path of movement across the lay at the mouth of the shuttle box and beneath the cover plate, the combination of a front guard plate secured to the la, extending well above the middle of the shuttle, presenting a forwardly curved inner end, and extended outwardly to form an inner front wall at the mouth of the shuttle box and a front guide plate secured to the lay, located entirely inwardly of the path of the shuttle feeler, having its inner end curved forwardly and downwardly to a point well forward of and below the path of the shuttle tip, and acting to direct the front wall of the shuttle into engagement with the front guard plate.

2. In an automatic filling replenishing loom of the type defined in claim 1, the combination of the front guard plate and front guide plate defined in claim 1 in which both plates are integral parts of a single structure having a depending base secured to the front. face of the lay.

In testimony wherof, I have signed m name to this specification.

PARKER J. JONES.
